Fracture & Splint Care: Complete Recovery Protocol from Injury to Return to Function
Immediate Post-Injury / Post-Operative Principles
Whether managed with splint, cast, brace, or surgical fixation, bone and soft tissue healing follows biological phases. Your role: protect the construct, optimize biology, prevent complications.
Phase 1: Acute Protection (Days 0–14)
| Domain | Actions | Rationale |
|---|
| Immobilization | Splint/cast/brace per protocol; crutches/sling; NWB/PWB/WBAT as ordered | Prevents displacement, allows hematoma organization → soft callus |
| Elevation | Injured part > heart level 23/24 hrs first 72h; then q2h | ↓ Hydrostatic pressure → ↓ edema, pain, compartment risk |
| Ice | 20 min on/40 off (barrier); cryocuff if available | Vasoconstriction, ↓ metabolism, ↓ pain, ↓ secondary hypoxic injury |
| Compression | Cohesive wrap / Tubigrip distal→proximal; monitor capillary refill | Limits edema, supports venous/lymphatic return |
| Pain Control | Multimodal: scheduled acetaminophen + NSAID (if allowed) + opioid PRN breakthrough | Prevents central sensitization; enables early motion |
| Skin & Cast Care | Keep dry (cast cover for shower); no objects inside; inspect edges daily | Prevents maceration, pressure sores, infection |
| VTE Prophylaxis | If NWB >2 wks: LMWH/DOAC per protocol + mechanical (SCDs, ankle pumps) | DVT/PE risk ↑ 10–20× with lower extremity immobilization |
Phase 2: Controlled Mobilization (Weeks 2–6)
- Radiographic healing signs: Periosteal reaction, callus bridging, trabecular continuity.
- Transition: Rigid → removable brace/boot; progressive weight-bearing (25% → 50% → 75% → FWB).
- Physical Therapy: AROM/AAROM → gentle resistance; proprioception; kinetic chain.
- Edema management: Contrast baths, retrograde massage, compression garment.
Phase 3: Strengthening & Functional Restoration (Weeks 6–12+)
- Open-chain → closed-chain progression (knee extension → mini-squat → step-down).
- Load management: Bone responds to progressive mechanical loading (Wolff’s Law).
- Sport/Work-specific drills: Plyometrics, cutting, lifting simulation.
- Outcome metrics: Strength symmetry >90%, hop test >90%, patient-reported outcomes (PROMIS, LEFS).
Nutrition for Bone Healing
| Nutrient | Target | Sources |
|---|
| Calcium | 1200–1500 mg/day | Dairy, fortified plant milk, sardines, kale, supplement if needed |
| Vitamin D | 2000–4000 IU/day (target 25-OH-D >40 ng/mL) | Sun, fatty fish, fortified, supplement (most need it) |
| Protein | 1.2–1.6 g/kg/day | Lean meat, eggs, Greek yogurt, legumes, whey |
| Vitamin C | 500–1000 mg/day | Citrus, peppers, berries, supplement |
| Zinc, Copper, Magnesium | RDA+ | Nuts, seeds, shellfish, whole grains |
Red Flags: Contact Provider Immediately
- Increasing pain unrelieved by elevation/ice/meds
- New/worsening numbness, tingling, coolness, color change
- Cast/splint: tight, loose, cracked, wet inside, foul odor
- Fever >101°F, wound drainage, spreading redness
- Calf pain, swelling, Homan’s sign (DVT)
- Sudden shortness of breath, chest pain (PE)
Return-to-Activity Decision Making
Based on clinical union (painless stress), radiographic union (3/4 cortices), functional symmetry, and psychological readiness – not calendar date alone. Clearance is a shared decision: surgeon + PT + patient.
